  1. 10.6 Three- Dimensional Figures I can name three-dimensional figures

  2. Vocabulary polyhedron cylinder face pyramid edge cone vertex sphere prism base

  3. A polyhedron is a three-dimensional object with flat surfaces, called faces, that are polygons. When two faces of a three-dimensional figure share a side, they form an edge. A point at which three or more edges meet is a vertex (plural: vertices).

  4. 5 faces 8 edges 5 vertices 7 faces 15 edges 10 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

  5. 6 faces 12 edges 8 vertices 5 faces 9 edges 6 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

  6. A prism is a polyhedron with two congruent, parallel bases, and other faces that are all parallelograms. A prism is named for the shape of its bases. A cylinder also has two congruent, parallel bases, but bases of a cylinder are circular. A cylinder is not a polyhedron because not every surface is a polygon.

  7. A pyramid has one polygon-shaped base and three or more triangular faces that share a vertex. A pyramid is named for the shape of its base. A cone has a circular base and a curved surface that comes to a point. A sphere has no base and one curved surface. All points on the surface are the same distance from a point called the center of the sphere.

  8. The figure represents a cylinder. Name the three-dimensional figure

  9. The figure is a rectangular prism. Name the three-dimensional figure represented by the object.

  10. The figure is a square pyramid. Name the three-dimensional figure represented by the object.

  11. Lesson Quiz 1. Identify the number of faces, edges, and vertices in the figure shown. Identify the figure described. 2. two congruent circular faces connected by a curved surface 3. one flat circular face and a curved lateral surface that comes to a point 8 faces, 18 edges, and 12 vertices cylinder cone
